Great ProductBy Johnon 4/13/2013

Brs gfo is the best value of all gfo. It pulls the phosphate out and keeps it down

Great product but attention to detain in packaging the product is lackingBy Glennon 4/11/2013

Great product. My first purchase of this product was exceptional in all ways, but my recent purchase was less than desireable. The 5 gallon container had GFO all over the outside of the plastic bucket and in the bottom of the shipping box.
Attention to detain was lacking!

I'm running 1.5 cups in the dual reactor for 200 gallons, which is half of what the BRS calculator recommends. The reactor can't handle much more per cartridge and still keep things flowing. I change it every two weeks, rather than use 3 cups and change monthly. So far so good with this system.

Eventually I want to get a separate reactor for carbon and then just run 1.5 cups in each side of the dual reactor, but the system is working so far for me.

Best price for gfo. You will not regret this purchase as your corals will thank you and so will your wallet

I used this in a filter sock and reactor, i recommend the reactor. Anyway, this stuff is great, it eats right through phosphates. No more algae!

Does what it should. My only complaint is the particle size, as it can work through the sponges in your reactor. Makes setting the flow a bit tricky. I would suggest starting with a little less than the recommended amount by the BRS calculator. GFO can and does release Iron into your system, so use only what you need. Saves your system from Iron (HARD to get back out) and your wallet, at the same time! Also, I run one gallon of tank water through my reactor, to rinse, when I change it out. Helps a lot with the fines.

I run this GFO in a mesh bag in my sump (no reactor), and it has helped with PO4 in my FOWLR. Very reasonable price, too.
